Albertín Aroldis Chapman de la Cruz (Spanish: [aˈɾoldis ˈtʃaβman]; born February 28, 1988) is a Cuban-born American professional baseball relief pitcher for the Boston Red Sox of Major League Baseball (MLB). He has previously played in MLB for the Cincinnati Reds, New York Yankees, Chicago Cubs, Kansas City Royals, Texas Rangers, and Pittsburgh Pirates and in the Cuban National Series for Holguín. Chapman bats and throws left-handed, and is nicknamed "the Cuban Missile", due to his high fastball velocity. A member of the 300 save club, Chapman is the all-time career leader in strikeouts for relievers.
Chapman pitched for Holguín domestically and internationally for the Cuba national baseball team. He defected from Cuba in 2009 and signed a contract with the Reds in 2010. Chapman made his MLB debut that season. He won the MLB Delivery Man of the Month Award as the best relief pitcher for July 2012, was named to four straight National League All-Star teams from 2012 to 2015. The Reds traded Chapman to the Yankees after the 2015 season, and the Yankees traded Chapman to the Cubs during the 2016 season. With the Cubs, Chapman won Game 7 of the 2016 World Series. He rejoined the Yankees after the 2016 season. He was named an All-Star three times with the Yankees and was named the AL Reliever of the Year in 2019. Following six seasons with New York, Chapman signed a one-year deal with the Royals before being traded to the Rangers at the trade deadline, winning the 2023 World Series with the team for his second championship. Chapman played a year with the Pirates in 2024 and signed with the Red Sox in 2025, where he was named to his eighth and ninth All-Star Game.
On July 11, 2014, Chapman broke the record, previously held by Bruce Sutter, for the most consecutive relief appearances with a strikeout, having struck out at least one batter in 40 consecutive appearances. Chapman's streak began on August 21, 2013, and lasted 49 consecutive games over two seasons, with the 49th and final game being on August 13, 2014. Chapman currently has the record for the fastest recorded pitch speed in MLB history, at 105.8 miles per hour (170.3 km/h), as well as the Guinness World Record for fastest baseball pitch.
Albertín Aroldis Chapman de la Cruz was born on February 28, 1988, in Holguín, Cuba. He lived in a three-room house with his parents and two sisters. Chapman's father was a boxing trainer and then later worked for the city. His mother did not work outside the home. Chapman's paternal grandparents had emigrated from Jamaica to Cuba in order to get a better education. The Chapmans, whose last name can be traced to English settlers in Jamaica in the late 1600s, were not a prominent family.
A friend of Chapman invited him to join a local baseball team at the age of 15. He began playing as a first baseman until the coach noticed that Chapman could throw well enough to become a pitcher, which Chapman began in 2003.
Chapman joined the Holguín Sabuesos of the Cuban National Series League for the 2005–06 season and played through the 2008–09 season. In 3272⁄3 career innings, Chapman compiled a 24–19 win–loss record, a 3.74 earned run average (ERA), and 365 strikeouts. For the 2008–09 season, he compiled a 11–4 record with a 4.03 ERA, 130 strikeouts, and 1181⁄3 innings pitched. He was used mainly as a starting pitcher during his time with the Sabuesos, although he made 11 relief appearances in the 2007 season, where he compiled seven saves.
After a failed attempt to defect in the spring of 2008, Chapman reported to Havana to meet with Cuban president Raúl Castro who gave him a conditional reprieve, suspending him for the remainder of the National Series season and also keeping him off Cuba's national team for the 2008 Summer Olympics but allowing him to return to the National Series and play in the WBC in 2009.
Chapman successfully defected from Cuba while in Rotterdam, Netherlands, where the Cuban national team was participating in the World Port Tournament on July 1, 2009; Chapman walked out the front door of the team hotel and entered into an automobile driven by an acquaintance. Gerardo Concepción defected from the Cuban national team in the same tournament. Chapman eventually established residency in Andorra and petitioned MLB to be granted free agent status.
On January 10, 2010, Chapman signed a six-year contract with the Cincinnati Reds worth $30.25 million. The Associated Press reported that the signing bonus totals $10.25 million, paid annually over 11 years, with an additional bonus if he became eligible for salary arbitration in 2012 or 2013.
Chapman began the 2010 season assigned to the Triple-A Louisville Bats, and made his professional debut with the Louisville Bats on Sunday, April 11, in Toledo against the Mud Hens, where he pitched 4+2⁄3 innings, giving up one unearned run, while striking out nine. Chapman made 13 starts with Louisville, pitching to a 4.11 ERA, and pitched to a 2.40 ERA after the team used him as a relief pitcher.
Chapman made his Major League debut August 31, 2010, in the eighth inning against the Milwaukee Brewers; his first pitch was clocked at 98 mph (158 km/h) as a called strike (which was promptly tossed to the dugout by catcher Ryan Hanigan, to be saved). In nine pitches he retired the side. He recorded his first Major League win on September 1 after pitching an inning of relief against the Brewers. Chapman threw the fastest pitch recognized by MLB on September 24, 2010, at Petco Park in San Diego, California. It was clocked at 105.1 mph (169.1 km/h) to Tony Gwynn Jr. in the eighth inning.
In Game 2 of the 2010 NLDS against the Philadelphia Phillies, Chapman allowed three unearned runs due to miscues of the outfielders. He got his first career postseason loss and the Reds lost the division series to the Phillies in a three-game sweep.
Chapman served solely as a relief pitcher in 2011, appearing in 54 regular season games and finishing the season with a 3.60 ERA. He also struck out 71 batters in just 50 innings of work that season.
Chapman was due to be introduced as a starter for the 2012 season, but preseason injuries to closer Ryan Madson and middle relievers Bill Bray and Nick Masset led manager Dusty Baker to put Chapman in the setup role. Interim closer Sean Marshall struggled early in the season, and Chapman was given the closer role in late May.
On July 1, 2012, Chapman was named to his first All-Star Game. Chapman won the MLB Delivery Man of the Month Award for July 2012, in which he recorded 13 saves while not allowing a run in 14+1⁄3 innings while striking out 31 batters—more than 60% of the batters he faced. It was the third month of the season in which he did not allow a single run. He was named the August Delivery Man of the Month. Chapman finished the 2012 season with a 1.51 ERA and 38 saves in 43 chances, recording 122 strikeouts and 23 walks in 71+2⁄3 innings.
In March 2013, it was announced that Chapman would be the closer for the Cincinnati Reds. He was an All-Star selection for the second season in a row. He finished the 2013 year with 38 saves, a 4–5 record, 112 strikeouts, and a 2.54 ERA.
During a spring training game against the Kansas City Royals on March 19, 2014, Chapman was struck in the head by a line drive from Salvador Pérez. The spring-training game between the Reds and the Royals was ended at that point with Kansas City leading 8–3. Chapman underwent surgery to fix a skull fracture above his left eye. A metal plate was inserted into his head to stabilize the fracture.
Chapman began the 2014 season on the 15-day disabled list. He was activated from the disabled list on May 10. Chapman recorded his 100th save against the Arizona Diamondbacks on July 29, 2014, becoming the eighth-fastest pitcher to reach the milestone. In the 20-pitch appearance, Chapman threw 15 fastballs, all of which were above 100 mph. On September 23, 2014, Chapman recorded his 100th strikeout in his 51st inning pitched of the season, making him the fastest pitcher ever to reach that milestone. In 54 appearances, Chapman produced 106 strikeouts with 36 saves going 0–3 with an ERA of 2.00.
